Objective caml (ocaml) is an implementation of the ml language, based on the caml light dialect extended with a complete class-based object system and a powerful module system in the style of standard ml.

camlp4 is a pre-processor-pretty-printer for objective caml. it offers tools for syntax (stream parsers and grammars) and the ability to modify the concrete syntax of the language (quotations, syntax extensions).

this package contains pre-linked executables and libraries for pre-processing and pretty-printing ocaml sources out of the box for various common needs.
